Abstract (en)

[origin: EP4112733A1] Provided is a method for synthesizing a chiral diamine compound. The synthesizing method includes: converting a substrate represented by Formula I into a chiral diamine compound in Formula I by using a transaminase, herein n=1~10, an R group represents an alkyl, a cycloalkyl, a heteroatom-containing alkyl, a heteroatom-containing cycloalkyl, a heteroatom-containing aryl, an amide compound residue, or an ether compound residue, and a hetero atom is at least one from among O, S and N; R1 and R2 are the same or not the same, the R1 and R2 are respectively and independently hydrogen, a C1-C3 alkyl, or an amino protecting group; and the transaminases are derived from a plurality of strains.The transaminases all have a relatively high reaction selectivity and activity on various substrates represented by Formula 1. By catalyzing and synthesizing a chiral diamine compound by using the biological enzyme, not only is the substrate scope wider, but the route also short and product yield high, thus greatly reducing production costs and reducing the production of an organic solvent and the three wastes.
